Functional features of PPR task management:
1. Good corrosion resistance: In addition to most oxidants, it can resist the corrosion of various chemical media, no rust, no corrosion, no electrochemical corrosion.
2. Good heat-resistant function: when the task water temperature is 70 C, it can be used temporarily. Professional consumption of direct-buried insulation pipe manufacturers, short-term use of water temperature to 95 C, hardening temperature to 140 C light weight. The density is 0.89-0.9g/cm3. The joint insulation of the directly buried insulation pipe is only one ninth of that of the steel pipe and one tenth of that of the copper pipe. Because of its light weight, the transportation cost and the construction intensity of the equipment can be greatly reduced.
3. Health is not toxic: PP-R data are composed of carbon and hydrogen, and no toxic heavy metal salt fluctuating agent is added. The health function of PP-R data has been tested.
The service life of PPR pipes with long service life is more than 50 years under additional operating temperature and pressure.
4. Water flow resistance is small: the inner wall of the pipe is lubricated without scaling, and the coefficient of friction is only 0.007, which is much lower than that of the metal pipe, so that the water flow can be improved by more than 30% than that of the metal pipe of the same specification.
5. Good heat preservation function: Because of the low thermal conductivity of PP-R data, the thermal conductivity of PP-R pipe is 0.21-0.24W/mk at 20 C, which is much smaller than that of steel pipe, so the heat preservation of PP-R pipe is good.
6. Small shrinkage force: Because the elastic modulus of PP-R data is small and the shrinkage force caused by temperature change is small, it is appropriate to adopt the direct burying and concealed laying method in the embedded wall and the floor.
7. Fragmentary bonding: PP-R pipeline stops bonding by hot-melt bonding, and connects the same material pipe and fittings into a whole. The tensile, bending and impact strength of the joint is higher than the strength of the pipe body, thus eliminating the hidden danger of water leakage.
